I certainly would not try that two point lift at home! Yes, the M62 Wreckers replaced the wartime Diamond T Wreckers being used by the Canadian Brigade in Northern Germany in the mid-1950s. In Germany, the new M-Series vehicles used what is now the CFR system while the older wartime vehicles all employed the domestic DND numbering system.
Of course you have to keep in mind that at the same time any RCAF M-Series vehicles used the RCAF vehicle registration system.
